APPARATUS FOR EFFECTING SEPARATION OF MATRICES AND SPACE-BARS IN TYPO- GRAPHICAL COIVIPOSING-MACHINES.

To all whom it may concern:

Be it known that I, CARL MUEI-ILEIsEN, a citizen of the United States of America, residing at 88 Chausseestrasse, Berlin, N. 4, in the Empire of Germany, have invented new and useful Improvements in Apparatus for Eflecting Separation of Matrices and Space-Bars in Typographical Composingldachines, of which the following is a specification.

This invention relates to apparatus for effecting the separation of matrices from space bars in typographical composing machines, whether such machines be adapted to produce separate type bodies each bearing one or more printing characters, or-as in the machines known commercially under the trade mark Linotype cast bars bearing complete lines of printing matter.

As the invention is particularly applicable to machines known under the aforesaid trade mark, the following description deals with it only in that connection. In these said machines the separation of the matrices from the space bars takes place in what is known as the space-band or space bar intermediate channel, the matrices being lifted out or withdrawn from among the space bars by means of the second elevator head with the ribbed bar of which the distributer teeth of the said matrices have previously been engaged by being slid thereonto in the longitudinal direction of the said bar. When the second elevator is raised to raise the matrices up to the distributor, the space bars are left behind in the space bar intermediate channel, by reason of the fact that the V-shaped notches of the said space bars have no teeth and do not en age with the above-named ribbed bar. A ter the matrices have been lifted clear of the space bars, the latter are returned to their magazine.

All the foregoing operations are carried out in the manner well known in the art, and the present invention provides for the attainment of the same result in a different manner and by different means.

According to the present invention the aforesaid separation of the matrices from the soace bars, withd rawn horizontally from the space bar intermediate channel, as distinguished from vertically therefrom, and the matrices are or Specification of Letters Patent.

Application filed July 19, 1910.

is effected by their being Patented Oct. 18, 1910.

Serial No. 572,664.

through preferably the back of the space bar intermediate channel, but in a machine having two magazines adapted to deal with different sets of matrices or for containing matrices of respectivel different fonts, the the matrices of the di erent fonts are withdrawn through respectively the back and front of the said channel.

When, in a machine arranged as last mentioned, matrices of different fonts are used for the production of mixed matter, the said matrices can be separated according to their fonts, at the same time as they are separated from the space bars; hitherto, similar conditions have involved two separate operations, one to separate the matrices from the space bars and the other to separate the different fonts.

In the accompanying drawings :Figures 1 and 2 show one embodiment of the method in which the matrices are separated from the space bars by withdrawal through only one side of the space bar intermediate channel. Figs. 3, 4: 5 and 6 show two embodiments of the method in which matrices of different fonts are withdrawn through respectively differentwalls of the said channel, and Figs. 7 and 8 are elevations of two different forms of space bars.

All the figures show the space bar intermediate channel in vertical section, Figs. 1, 3 and 5 showing the respective devices in posit-ion for receiving the matrices and with the said matrices attached thereto, and Figs. 2, 4L and 6 showing the said devices with the matrices separated from the space bars. After the casting operation, the composed line of matrices 1 and space bars 2 is received in the space bar intermediate channel 3 in the ordinary way. This channel has, below the rearmost space-bar guiding ledge 4, an opening 5 the length of which corresponds to that of the longest composed line and its height is at least that of the matrices 1.

Each of the matrices 1 is provided in its rear vertical edge, with a dovetail recess 6 which, as the composed line is being moved into the channel 3,is threaded on to a dovetail rib 7, which is capable of being moved in a direction perpendicular to the length of the composed line. As shown in Figs. 1 and :1, the dovetail rib 7 is supported by two arms or matrix carriers 8 fast to two guide bars 9 respectively (only one of these guide bars represented, the other one being directly behind, and obscured by that which is shown. The guide bars 9 are free to slide perpendicularly to the direction of the length of the composed line, in guides 10, 10 and springs 12 arranged between the arms 8 and the guides 10 constantly tend to move the said arms and the dovetail rib 7 rearward into the separating position in which they are shown in Fig. 2. The rib 7 is held in the position in which it is shown in Fig. 1, against the influence of the spring 12 by a pusher 13 adapted to slide on a guide rod 14 fast to the intermediate channel 3, and which pusher is connected by a link 15 with the longer arm 16 of a two-armed lever 16, 17, the arm 17 of which is acted upon by a cam 18 on the cam shaft 19 of the machine. A spring 20, which acts on the longer arm 16 of the lever 16, 17, holds the shorter arm 17in constant operative contact with the lifting cam 18 and it is of greater strength than is the spring 12. By the foregoing arrangement the rib 7 will be moved into the receiving position shown in Fig. 1, as soon as the de pression 21 of cam 18 is presented to the lever arm 17 at which juncture the spring 20 draws forward the lever arm 16. Then the cam depression 21 leaves the lever arm 17, the lever arm 16 and slide 13 will be moved rearwardly against the influence of the spring 20 and the arm or matrix carrier 8 will thereby be left free to be moved rearwardly by its spring 12, and when thus moved it will carry with it the matrices 1 which then are attached to it by means of the dovetail recesses 6 and rib 7.

By the just described means, the matrices 1 are withdrawn to the rear of the channel 3, leaving only the space-bars 2 remaining behind in the said channel, as shown in F ig. 2. After the matrices have thus been moved clear of the space bars, the latter are, in the usual way, carried back to their magazine, and simultaneous with this operation, the matrices 1', by their well-known toothed upper recesses, can be engaged with a ribbed bar of the second elevator which latter would raise them up to the distributer which in turn would distribute them into their respective magazine channels.

In the apparatus so far as described, it is assumed that the guides 10, 10 are stationary, being fast to any suitable fixed part of the machlne, but in a simpler arrangement, as re resented in the several examples illustrated in the drawings, the said guides 10, 10 form part of the second elevator head 22 pivoted in the usual way to the second elevator lever 23. The upper part of the channel 3, or other suitable part of the apparatus, may constitute a stop or stops 2d for causing the second elevator 22 to properly register with the said channel. During the descent of the second elevator 22, the arms or matrix carriers 8 are in their rearmost position, so as to clear the channel 3, and on reaching its lowest position, the said arms 8 are moved forward by the spring 20, so that the matrices 1 may be received on the rib 7; after the matrices have been thus attached to the rib 7, it and the arms 8 are moved rearward by the cam 18 as already fully explained.

The second embodiment of the method shown in Figs. 3 and 4 dilfers from that previously described by having two dovetail ribs 7, 7 movable in relatively opposite directions through openings 5, 5 in respectively the back and front walls of the spacebar interi'nediate channel 3. Each of the dovetail ribs 7, 7 is in rigid operative connection by arms 8, 8 respectively, with a bar S) or 9 capable of sliding in guides 10, 10 in a direction perpendicular to the direction of the length of the composed line on the elevator head 22. A spring 12 be tween the arms 8 and 8, constantly tends to press the said arms away from each other. The matrices l and 1 are each provided on one vertical edge with a dovetail recess 6, 6 respectively to engage with the respective dovetail rib 7, 7 the other vertical edge of the said matrix being provided with a rectangular or equivalent recess 25, 25 into which the other rib 7 or 7 freely enters without engaging therewith. Aceordingas the matrices are provided with the dovetail recesses 6 or 6 on one side or the other, they will be moved rearwardly or forwardly by the respective dovetail rib 7 or 7*. The two bars 9 and 9 are operatively connected to each other in such manner that as one is moved in one direction the other is moved in the opposite direction. This is effected, in the example shown in Figs. 3 and 4 by a toothed wheel 26, rotating on a fixed pivot i7, engaging with racks 28, 28' on the said ars.

Figs. 5 and 6 show another embodiment of the improved method. Here the arms or matrix carriers 8, 8 carrying the ribs 7, 7 are each connected to the elevator head 22 by two links 29, 29 these links 29, 29 are of equal radial length, and the two inner ones are, at opposite sides 80, 30, of their respective pivots, comiected together by a link 31. A tension spring 12 acting on the link 31, constantly tends to move the arms 8, 8 and ribs 7, 7 outward from each other, into the positions in which they are respectively shown in Fig. 6. The movement of the ribs 7, 7 of Figs. 5 and 6, toward each other, is effected in the same way as in the example illustrated in Figs. 3 and 4.

The space bars 2, for use with this invention, are provided each with a rectangular recess 32 in its rear edge only as re )resented in Fig. 7, as when it is intended or use in the arrangement shown in Figs. 1 and 2, or with two such recesses 32, 32 one in its rear edge, and the other in its front edge, as shown in Fig. 8, as when it is intended for use in the arrangements shown in Figs. 3 to 6, these recesses being of sufiicient size to avoid engaging with the dovetail ribs 7 7*, the said recesses being situated beneath the usual sustaining shoulders 33 of the space bars.
